To all Iwhom 'it 'mayconcern.-4

' Beit known that we, J. A. WooDWARD, S. S. WOOD- WARD, and THOMAS MA SON, of Sandwich, in the county of De Kalb, and State of Illinois, have invented an Improved Oultivator; and we do hereby 4declare that the following is a full, clear, and exact description thereof, which will enable others skilled .in the 'art to make and use thesame, reference being had to the accompanying drawings, and letters marked thereon, making a part of this specification, in which- Figure l is a perspective representation of our improved cultivator.

Figure 2, an enlarged perspective -view of the at` tach`ment,for fastening the beams to the frame.

Figure 3, an enlarged view of the lower end of the standard, showing how the shovelsare attached.

Figure 4, `a view of the band used with the clamp, shown at fig. 3,120 hold the shovel in place.

.The object of the present invention is to improve thel cultivator patented 4by us, September 15, 1868; an

The nature ofthe improvement consists-4 First, in the novel construction of the parts used to form the compound joints, with which the beams are connected to the forward end of the cultivator-frame.

Second, the construction of the clamps, with which the detachable 'handles are fastened to the beams.

Third, the use of inclined standards, so arranged, that the segments over which the lifting-chains pass, are brought directly over the shovel-beams.

A represents a frame, mounted on wheels A', whose axle-arms B are pivoted to the sides A of the frame, substantially in the same manner as the arms shown in our patent above referred to.

The hinged seat C is also the same as the seat used in said patent, andv is, therefore, no part of the present invention.

AS S represent thesides of the. metal frames, which have. lugs e, turned outward, and fastened to the under side of that part of the frame shown at B, and which are rigidly attached to horizontal plates U T, placed such distances apart, as to support bolts V, of such length as will allow friction-clutchesZ Z to have a vertical adjustment, and thereby bring the forward ends of the beams J, to any required height above the 'surface of the ground, the plates U having two or more holes, W, and the plates T two or more holes, X, to receive the bolt V, when the' beams J 'are to have a lateral adj nstment.

The friction-clamps Z-Z, are made in two parts each,

and provided with concave jaws a, which are made to clasp the boltV firmly, by means of bolts and 'nuts b, put through the clamps Z Z, as shown at fig. 2, and with short pivots 'm at their opposite ends, which'have bearings in plates g, attached to the forward ends of the beams J. Bolts, however, may be used to hold the clamp to the plates g, instead of the pivots m, if desirable.

' By this construction and arrangement, any desired adjustment of the beams J can be made, by simply loosening the nut on the bolt b, and placing the jaws a further up or down on the bolt'V, or by placing the bolt in the Vside holes \V X.

The handles d d are held in place by means of cast or wrought-iron sockets ff, fig. 1, which are fastened to the sides of the beams J, and by plates-p, which are fastened, at their rear endsL to the beams, .and firmly clamped to the handles d, by means of bolts n, which pass through the plates, and intothe beams, at the front sides of the sockets ff. By this means, the haudles can be readily removed, when the operator is to ride, by loosening the bolts n.

Two standards, D, are supported by the frame-pieces A A, and they are so inclined inward, as to bring the pivoted segments F, tig.v 1, directly over the beams J.

This is done, in order that the chains t, which support the beams, may hang iu vertical positions when the shovels are moving in the middle ofthe rows.

Ratchets E, levers Gr, and spring H, having the ordinary construction, are'used, in connection with the segments F and standards D, to raise and lower the beams J, in the usual manner.

Having thus described my invention,

\Vhat l claim, and desire to secure by Letters Pat-v ent ofthe United States, is-

1. The combination of the clamps Z Z, pins V, frame S T U, and beams J, as and for the purpose set forth.

2. The combination of the sockets j' f, handles al, plates p, and beams J, said plates being arranged to clamp the handles to the beams, as set forth.

3. The inclined standards D, in combination with segments F, ratchets E, levers and springs G H, beams J, chains t, clamps Z, and frame S T U, as shown and specied. l.
